DESMONDJOSEPH J HART DISPENSER BIN CARTON It isan object of this invention toprovide a dispenser bin carton having a bin front movable between aclosed bin position and a bin delivery position, and characterized bybin sides movable between carton flaps in such a fashion that theproduct within the carton does not interfere with bin opening andclosing. 3

Another object is to provide a dispenser bin carton fonned from aunitary cut and scored blank, and characterized by a bin front having adouble thickness for the reinforcement thereof.

Yet another object is to provide a dispenser bin carton characterized bya movable bin front which is formed as a part i of the front panel ofthe carton, the panel being adapted to be separated into a fixed portionand into a movable portion forming part of the movable bin, the movablebin front having a double thickness for reinforcement thereof.

FIG. 12 is an isometric view showing the steps in forming the cartonaccording to'the secondembodiment of the invention.

The dispenser bin carton according to a first embodiment of theinvention is referred to by the reference numeral 15 and is formed froma unitary cut and scored blank 15A seen in FIG.

2. The carton 15 and blank 15A seen in FIGS. 1 and 2 are comprised of afront panel 16, a toppanel 17, a back panel 18,

and a bottom panel 19 all of which are hingedly connected to I eachother along score lines 21.

Front panel 16 is divided into a movable bin front portion 22 and afixed front panel portion 23, the former being defined by parallel cutand nicked lines 24 and a transversely cut and nicked line 25 extendingacross the front panel 16 and between the cut and nicked lines 24. Anopening tab 26 for the bin front portion is defined by spaced cut lines27 and a score line 28 parallel to the cut and nicked line 25.

A glue flap 29 is hingedly connected to the movable bin front portion 22along a score line 31, and a bin front reinforcing panel 32 is hingedlyconnected at the other end of the blank 15A seen in FIG. 2 to the bottompanel 19 along a score line 33.

It may be noted at this pointthat the inside face of the cut and scoredblank 15A is shown in FIG. 2. Glue flap 29 is glued to the inside faceof the bin front reinforcing panel 32, see also FIG. 4, score lines 31and 32 being substantially in register.

Bin front-reinforcing panel 32 is also glued to the movable bin frontportion 32 adjacent score line 21.

' Front panel 16 is hingedly-connected to side panels 34 along parallelscore lines-36. In order to provide for hinging movement of the movablebin front portion 22, the cut and nicked lines 24 areeach provided atthe ends thereof with a hinging nick 30 extending into side'panel 34. Itmay be noted that cut and nicked line 24 is coterminous with the scorelines 36.,

Each of the side panels 34 is provided with'a tuck-in flap 37 hingedlyconnected to side panel 34 along a score line 38, and

each ofthe tuck-in flaps 37 is provided with a lock slot arrangement 39cooperating with lock tabs 42 formed at each side of the back panel 18.

Bin side panels 47 are foldably connected to the bin frontreinforcingpanel 32 along score lines 43, and each bin side panel 42 has a strike44 adapted to engage with'the inner face of the fixed front panelportion 23 when the carton 15 is assembled and in the delivery positionseen in FIG. 3.

-Stiffener flaps 46 for carton are foldable upward with respect to thebottom panel 19 along score lines 47, and upper stiffener flaps 48 arehingedly connected to the top panel 17 along score lines 49 and arefoldable downward alongside stiffener flaps 46'.

In the steps of forming the carton according to this embodiment of theinvention, glue flap 29 is glued to both the bin front panel 22 'and thebin front reinforcing panel 32 to provide a carton sleeve. After thesleeve is formed in the manner described, flaps 48 are folded downwardalong score lines 49 into position. Bin side panels 42 are then foldedinto position along their score lines 43 into position alongside thefolded down stiffener flaps 48 extending downward from the top' panel17. Lower stiffener flaps 46 are folded upward along their score lines47 from the bottom panel 19 along the inside of the bin side panels 42.Closing of the carton is completed by folding of the side panels 34 withrespect to the front panel 16 along the cut and nicked lines 24 andscore lines 36, side panels 34being secured tothe back panel 18'bytuck-in flaps 37 at the lock slot 39'andlock tab connections 41. Thecarton vention is referred to by the reference numeral in FIG. 12,

and is formed from a cut and scored blank 55A seen in FIG.

11. The construction of the carton seen in FIG. 12 is identical to theconstruction of the carton seen in FIG. 1 except that= tuck-in flaps 37are dispensed'with. In lieu thereof side panels 56 are hingedlyconnected to the rear wall along score lines 57.

In forming the carton according to the second embodiment of theinventionupper stiffener flap 48 is first folded into position and bin side panel42 then folded into position against the folded down upper stiffenerflap 48. As with the embodiment seen in FIG. I, stiffener flap 46isfolded upward with respect to bottom panel 19 againstthe bin sidepanel 42. Side panel 56 is then folded against the positioned panels 42,46, and 48 and side panel 34 is then folded against side panel 56 thelatter being glued to side panel 56. The structure according to eitherembodiment of the invention prevents product interference in openingandclosing of the bin front panel 22, the bin side panels 42 always movingbetween panels in such a fashion that the bin side panels are isolatedfrom the contents of the carton.

An important factor of the invention is the fact that the movable binfront portion has a double thickness preventing bowing when opening andclosing.
